To all whom it may concern. 1

Be it known that'l, MAURICE R'. KoHN, a` citizen of the United States, residing at the city of' St. Louis, State of Missouri, have invented a certain new and useful Improvement in Valves, of which the following is a specification, reference being had tothe accompanying drawing, forming a part thereof.V l

This invention relates to a certain nevi.'` and useful improvement 1n valves, the principal object of my present invention being to provide a siipleahd efficient accessible. valve having 'parts and' comprising al valve-member adapted to be automatically held to its seat in valve-sealing or closing position under the outward pressure compressed air or other Huid Within the con-- .aining vessel or receptacle and, to be un seated under the inward pressure or induence of the fluid when the said vessel or other receptac e is being lled or inflated..

With the above and other objects inV view, my present invention'resides in certain novel features of form, construction, and combination ot' parte, all as will hereinafter be described and afterward pointed out in the claim.` i' rMy present lvalve is especially use'lul in connection with the innertubesot" aut-omobile tires and the like adapted to be inflated by and to contain compressed air and will be here sol described; but it is .to be understood that ymy neuf valve may equally vvell e employed inconnection with other vessels er receptacles and with other duide. i

-ln the accornpjinying drawing, Figure l is a vertical sectional view of a valve embodying my preferred form; i

Fig, 2 is a plan vieyvoi' the apertured disk forming part of theY valve and which is adapted to provide a support or rest for the valve-closingn lation orlling of the tire-casing; vessel;

Fig. 3 is .a cross-sectional vieiv through the valve on approximately'lthe line 'l-3, Fie 1; e

Normally an internally threaded protecting-cap t) is threaded upon the easing l, as shown.

The. noodilied forni of my valve shown in Fig. l is substantially the same as the preferred form of valve shown iu Fig. l, exeept that the valve-memlnn proper in this 'form of valve is in the torni oli a cylindrical bloot. l0 of suitable material annularly beveled or eone-shaped at its Vupper end, as at ll, to operativelyl engage 'die inner wall o't" the mouth-portion l' o'l the nozzleanember 6 when in valye-elosing position. '.lhe blork or member ll() is further recessed on ite un der tace, as at '12, to receive the upper end of a short piu or stem lf?, lixed at its lower end in the, a-pertured dial; fr, upon which pin or stem 13 the block or member it) is slidable into and outy oli valve-eloeingposition.

The modified torni ot valve shown in Fig. (5 (litters 'from thel preferred form ot valve shown in Fig. 1 in that the internally threaded counter-bored portion 3b ot' easing,r l is Soi'newhat extended to reeeive a plurality of nozzle and valve-members proper. as Shown. Fitting within easing' l" and resting upon the shoulder at the lower end of' counter-bored portion il, is a similar apertured dink 5. rThreaded within Said counter-bored portion 3" to engage upon the Upper tace ol dish 5, isa nozzle-member 14 formed internally with a beveled enlargement 15 to provide the nunnber lf'l: with a. contracted mouth substantially Similar to .theeontraeted mouth ot' nozzle--niember G.

Loosely disposed within the member 14 to "heee seat in itssaid contracted mouth to close the valve. is a sphere tt. Fitting within Said emlnterelmred portion il" above said member ll, iS an additional dish 5 and nozzlen-iember 6 with its sphere 8. substantially similar in. all reepeete` to the disk and nozzleanember and Iapher'o 8 ot' the preferred 'form ofyvalve eho'wn in Fig. l. ln this form ot' my valve, the upper sphere 8 normally performs no t'unetion, the lower sphere 3 opening,` and closing the valve as before described in connection with the torni of valve shown in Fig. l.. Should, however, the lower Sphere 8 fail to perform its function, then the upper sphere S will come into play to properly open or close the valve.

lA am aware that minor changes in the torni. eonfiitruetion, arrangement, and combination ot the Several parte ot mynew valve may bri made and substituted 'for those herein-Shown and described without departing vtrom the nature or principle of my invention. i

llaving' thus described my invention, what l claim and desire to Secure by Letters Patf ent is:

A valve, oomprisiiig` a tubular easing. said aeingr at one end beingeounterbored and provided with int anal serew-tlueads its entire depth terminating in a shoulder, an apertured diet: .teated within the easing upon said shoulder, a tubular nozzle member havingl a eontraeted. cone-shaped mouth portion at its outer end and an externally serewthreaded straight portion aty its lower end ot" subetantially the same depth. as 'the eoimterlmre in said easing and adapted to be eerewed into the threaded eolmterbored end ol'I the easing and its inner end adapted to dirertly .ulgagg'e said disk to hold it in place nponsaid shoulder, and a valve proper loosely disposed in the nozzle number and adapted to eloeo the valve under outward prensure.v the said disk Serving aC a support for the. valve proper when in open position. ln testimony whereof, l have Signednmy name to thie specification.
